Answer:

LSA = 532 yds ^2

Step-by-step explanation:

We do not add the triangles in because they are the bases and the bases do not get added in the lateral surface areas.

From left to right

Rectangle 1

A = lw = 9.9 *20 =198

Rectangle 2

A = lw = 6.8 *20 =136

Rectangle 3

A = lw = 9.9 *20 =198

Add them together

198+136+198

532

LSA = 532 yds ^2

Gabby wants to spend exactly $2.00 on pencils and erasers, hence:

0.15x - 0.1y = 2 (1)

Therefore x = 10 and y = 5

Therefore she bought 10 pencils and 5 erasers.
